I don't disagree, but I think they are focused on their bread and butter, which is the mobile market. A 48Vdc 240Vac unit is not essential for that market.

@@MobileSolarConsulting It's really nice to have, though. Even if you just use the two 120VAC legs separately most of the time. It gives you a lot of options in the same amount of space and at roughly the same price point, particularly easier (thinner) wiring and 240VAC AC charging on the input side all in one neat package. In anycase, YMMV. But that' what I'm waiting for from Victron. They don't have a lot of good 48V options yet so right now I have to use a chargeverter to really push battery charging. -Matt

@@junkerzn7312 Agreed! The chargeverter is a nice solution. Even on systems where we have 2 x Victron Inverters in split phased, but an Onan generator with 2 120Vac lines that are In-Phase (not a true 240V source), sometimes we will separate L2 from the generator and connect it to a Chargeverter to speed up generator charging.

Thanks Alex! Glad you are enjoying boondocking.

No, but you can use the "safety switch" assistant, which is almost the same, if you know how. If not, schedule a consultation with us and we will teach you.

Thanks!

Tbh it seems like a lot, but I use every bit of the system. I like my trailer nice and chilly, and the 3 air conditioners draw a lot of juice!

Off-grid homes, when designed/built carefully, can be very energy efficient. RV's are not built to be efficient, unfortunately. It is a pretty funny comparison though.

Nice, sounds like you have a great system!

This is correct, but does not apply to mobile applications like RV's, vans, or boats. If you are using this in a Grid-connected residence scenario, where you wish to sell power to the utility company from your solar array/battery bank, then the older Multiplus is not an option for you.

This has a relay that you can program to close when you want the generator to start, but you usually need an additional accessory to convert that relay to a signal the generator understands. Call us and we can suggest the right part for your generator. Depends on the model. 561-320-2842

​@@MobileSolarConsultingwill any generator work? A dual fuel gas, inverter generator 3000 watt? I have read conflicting information and would love to know.

@@evertking1 If you are just using a single inverter, then yes, any 120V generator will work. You will want a way to dial down the AC input current limit though (GX Touch 50 or Digital Multi Control).

They can do that, yes, but depending on the generator, there are usually additional parts required. Please contact us for a recommendation. 561-320-2842 or email info@mobilesolarconsulting.com

It was not super difficult to re-route the shore wiring but it was time consuming. You are correct, that was meant to say 200ah Smart Batteries.

Congratulations on your charger that you built - sounds very effective. In our area, it is very common to have 90F weather with high humidity and we use the IP65 chargers outside for 2-3 days straight without issue. They certainly get warm, but they don't break. We've had ours for over 5 years now.

Specifications sheet, and our measurements, show 94-96% efficiency depending on the charger. Perhaps you are considering the full output of your generator? Your generator will throttle it's output when there is a lessened demand.

@@MobileSolarConsulting Well you are wrong. I use Fluke professional AC and DC wattmeters. At rated output, watts in at 230Vac and Watts out at 12v DC efficiency is 70% for all victron models, and the multiplus in charge mode too. Let them warm up for 10 minutes!

We are happy to help with this, but you need to call or email. TH-cam comments are not managed by our engineers or technicians. Thanks!

If you want to run this while you are not driving, then yes, you need a battery for that.

That is a pretty specific question. I would recommend calling us at 561-320-2842 and ask for Matt. He can answer that for you.

​@UKsystems that is not always the case. Not all RV's are built the same way. Depends on the mechanism the manufacturer used to combine the house and starter batteries, often referred to as a BIM. Some do not use a BIM at all, therefore having no connection between starter and house. This is specifically the case on many older RV's.

@@UKsystems Of course, but we were replying to the comment above about what appears to be a factory system without much modification. This is why telling the customer to call so we can discuss, instead of giving a shotgun approach answer, is the best bet here...

@@MobileSolarConsulting I will email you guys now, and follow up in the morning with Matt. Thanks!

Positive wire lands on the Smart Battery Protect output and negative wire lands on the Shunt output.

Rumors suggest 2025

Glad it was helpful!

Yes.

The owner is the same guy you see appearing in the TH-cam videos from Nomadic Cooling. He is clearly not Chinese. As far as the production location, we do not know or care where they are produced as the quality of the units is top notch.

if only...

Technically, yes, you should use a smart battery protect, and connect the allow to charge signal from the BMS to the H pin. In practice, if you have the Blue Smart Charger set to smart lithium mode, and you are confident the batteries will not be facing extreme temperatures, it is going to be fine to skip the BMS.

@@MobileSolarConsulting thanks for the fast reply! I’m putting together a parallel Victron battery bank, and the Victron lithiums are recommended to be initially charged before use in the manual, so my question is, if I’m wiring them in parallel do I still need to charge each battery before the install? Or can I hook the batteries up to the system right out of the box and just make sure to charge them before actually using the system? The manual is not clear if the batteries need to be installed at the same charge if in parallel. I hope this makes sense!

@@Ajjakakkaka It is best to charge each battery separately before installation. For further technical support, please call or email.

What company did you email? Victron is based in the Netherlands, and they do not really have customer facing technical support. They sell through distributors (like us!), so wherever you purchase your products is the best place to ask the questions. This is why it is important to support independent sellers instead of amazon. The 3 outputs means it will charge 3 separate battery banks of the same chemistry. This is mainly useful on boats where they often have an engine starting battery, a house battery, and a thruster battery (all AGM, all same voltage). This would not work properly if the batteries needed different charge profiles (example, one lithium bank and one lead bank) because it charges all of them with the same settings. It does keep all 3 batteries separated though, so your house bank could not drain your starter bank, for example. They do not have varying amperage outputs. All 3 have 30A output available, but the total is also 30A, so this is divided between the banks based on whichever needs it the most. If you have further questions, please give us a call!

Sort of...with a 4 terminal unit(3 positives and 1 common negative) you can charge up to 3 battery's at the same time...if it's 30 amp unit you'll get 10 amps per terminal with 3 battery's on charge...if only using 2 outputs then 15 amps per output...hope that helps

Yes, you can.

It technically does, but they do not provide any instructions on how to do this (ie. RJ45 pinout, which ports need to be terminated, etc) so after about 3 hours of attempts, we skipped it as it is not required.

Thanks for sharing your setup and your experience. Sungold is one of the cheapest brands on the market, for which we get calls all the time asking us to replace broken units. I'm shocked to hear it is still working 2 years later. I understand that you are cutting the power available in your main panel by half when on shore power. That is not acceptable for most of our customers. Most people are either paying quite a bit for labor or spending a lot of their own time, so the marginal increase in parts cost is well worth-it for the ideal solution. I do not recommend Sungold. In previous years, we attempted to sell cheaper brands, only to be bogged down by numerous warranty requests from manufacturing defects. We now recommend only the most reliable products and solutions.

@@MobileSolarConsulting While it's true that high frequency inverters, like my Sungold power are easily killed by running high inductive loads, like high current motors and A/C compressors, if you don't run these kinds of loads (we have a Micro Aire soft start on our rooftop A/C and a mini split that ramps up slowly) and operate them below their rated capacity, the capacitors will last much longer. My particular unit came with a 3 yr. warranty. Some only have 2 yrs. while they also sell low frequency units with up to a 5 yr. warranty. Of course, one could parallel 2, 3kw or 5kw Sungold Power units if needed, or just buy a 6000w split phase low frequency model for around $1k (one of the best deals going) if that better suits your needs. The point is that people have options. Unfortunately, I don't think Victron makes a 48v off-grid charge controller, much less an all-in-one that will handle the 500 volts of DC input I needed. One of the reasons I chose to go with Sungold Power and not one of the cheaper brands out there like Mr. Power is I met a gentleman in Quartzsite a couple years ago who was a full timer like me who had been using his Sungold Power inverter since 2015 and it was still going strong. No doubt Victron makes nice reliable units, just like Mercedes Bends makes nice, reliable cars. But you pay a premium price for both of them. This is why I drive a Chevy. Is it as good as a Mercedes? Nope, but I've got 450,000 miles on mine and it's still running. We're retired and living off of a meager SS check, which dictates our choices - and being retired I have much more time than money. If I were an installer, I would only recommend top of the line items with the least warranty claims too. After all, I'm not paying for them, my customers are, and the less equipment problems I encounter, the better reputation I have. But if you're on the other side of the equation looking to get the largest off grid system you can afford, you might make different choices. It's like batteries. Why pay for pre-built batteries when you can get more for less by building one yourself? The last battery I built cost me under $110/kwh with a smart BMS, compression fixture, etc. made from the latest MB-31 330ah EVE cells. It has a more compact footprint too. For comparison, Battleborns and Lion energy batteries cost over $700/kwh and Victron batteries are $450/kwh. Saving money like this allowed me to build the huge solar system on my motorhome for only $10k. I'm sure you would have to charge at least twice if not 3 times as much to build a system the size of mine with 5,020 watts of solar (a 4,400w rooftop array and a 620w liftable side array), 23.5kwh of batteries (a 7.1kwh 12v battery and a 16.4kwh 48v battery), 6kw of PSW inverted power (a 5kw, 48v inverter and a 1kw, 12v inverter), plus aluminum racking, wiring, breakers and everything else a system this size requires. I realize that a professional installation with quality components doesn't come cheap. I was just offering another option for those out there who are trying to make do with less due to budgetary constraints, especially if they are designing a system where Victron components don't meet the specs they require.

@@SuperSushidog Great, thank you for your input.

Hello, what do you mean by soft? The wires are insulated and flexible.

​@@MobileSolarConsultingYes, that's what I meant...flexible...that's the right word :) and will they stay flexible even in sub-zero winter temperatures?

@@lacike767 Yes, the cables are good quality, they will stay flexible even in cold weather.

​@@MobileSolarConsulting...because the short cable with the eyes seems to be quite hard...also the clips and the button are of good quality please?

@@lacike767 Everything on the charger is extremely high quality, including the wires and connectors.

Thanks!

Yes, it cools the entire van, even 170 extended sprinters with very little insulation here in FL on a hot day. If it's not cooling well, start by sealing any gaps, closing windows and doors, using reflectix on windows. Next insulate your van. If that does not do the trick you might have a faulty unit! We've never seen it fail to cool the entire van.

@SuperSushidog nice job to you too! Next time we will probably use the 5kW multi's, so the clients can power 3 x AC units at a time, and charge even faster from shore/gen.

@swishzonetech2551 This was actually filmed using a potato with seran wrap over it, so with that said, we were pretty impressed with the quality.

@@MobileSolarConsultingtactful response! Love it

This charges a 300ah 12V battery using the RV's converter. That is overkill and unnecessary for the 12V side, but the onwers already had the batteries, so no reason to toss them.

Ballpark $20K installed cost. Exact cost varies for every RV.

Thats correct, it does not hurt but is not necessary.

They help prevent dust/water from entering the multiplus. That is where the wires enter.

Hey thanks for the question! That info is in the description. This install was around $12,000 parts and labor included. Doing it DIY would be about $7,500-8,000 for parts.

@@MobileSolarConsulting Sorry...totally overlooked the price listed right there in the description - just went directly to parts list. 😂 Appreciate the reply.

There should be a combined ground busbar, where the ground of the starter battery and lithium battery BOTH connect. The Orion also connects here. If you need a diagram for your system, please contact us.

They are indeed 3000VA however the real power (wattage) depends on the power factor of the load.

While I agree that the marginal price difference makes the bigger systems more worthwhile, we have to respect that not every client has the budget or the need for it. With that said, Victron has not yet released a single 5kW unit with 240V passthrough, so we instead use 2 separate 3kW or 5kW units, which does increase equipment and labor significantly.

Yes! Give us a call to schedule an appointment 👍 561-320-2842

What specifically would you like to be more "finished" ?

Yes, absolutely.

There are a ton of factors, so it varies greatly. The average customer spends in the ballpark of $20K. 12V versus 24V does not really impact cost.

We do not ship internationally. Sorry about that.

This does not have an air "exhaust" so it does not do the job of a maxxair fan. If you'll be cooking inside your rig a lot, a Maxxair fan is a good idea, in addition to the VELIT. Most other AC units are the same in this regard.

It's possible but it would take some serious adaptation. I wouldn't recommend it and the standard parts that come with it would not be enough to cover it.
